First I’m going to share something I posted here a couple of years back, because it really worked for me. In 2015 I wrote:
I did a kind of “moral inventory” a while ago as I was beginning to immerse myself in LHP philosophy and as part of it, I rooted out everything I could where my actions had been out of integrity or against my own ethics.
In some cases I found I did have redundant programming holding me back, and could actually clear the slate of some things where I’d been carrying a nagging feeling of guilt - and, in other cases, I’d just acted in shitty ways from expediency.
I think 90% of anything, not just magick, is to get your head straight, not to become a perfected person - no such thing - but to know what your strengths and weaknesses are (they’re usually the same thing, but that’s another topic) and what makes you tick, or ticks you off.
Doing it non-judgementally by abandoning all the “shoulds” you may have been given by parents, teachers, politicians and preachers etc., and with a sense of humour and self-compassion, makes it less scary to dig pretty deep and encounter your own peculiarities.
So maybe making amends of some kind will help you to close the chapter.
Once you’ve done that, consider the ritual above and maybe a cleansing bath at the New Moon, or some other ritual that is created by YOU because that way, it works with your internal symbols and archetypes, for maximum power:
